Abstract

A display controlling apparatus that is capable of communicating with an image processing apparatus that sends image data to the display controlling apparatus in response to a notification from the display controlling apparatus, includes the following elements: a sending unit configured to send the notification to the image processing apparatus; a first receiving unit configured to receive the image data sent from the image processing apparatus in response to the notification; and a first computing unit configured to compute a first time required to display the image data received by the first receiving unit. The sending unit sends a new notification to the image processing apparatus at a timing based on the first time computed by the first computing unit.

Claims

exact text as granted — not AI-modified
What is claimed is:

 a capturing unit configured to capture image data; and 
 a sending unit configured to send image data captured by the capturing unit to the display controlling apparatus determined as the representative apparatus by the determining unit. 
 
     
     
       2. The image processing apparatus according to  claim 1 , wherein the receiving unit is configured to receive information related to each display controlling apparatus from each display controlling apparatus, respectively. 
     
     
       3. The image processing apparatus according to  claim 1 , wherein the plurality of display controlling apparatuses includes projection apparatuses. 
     
     
       4. The image processing apparatus according to  claim 1 , wherein the information related to each display controlling apparatus includes a respective capability of each display controlling apparatus. 
     
     
       5. The image processing apparatus according to  claim 4 , wherein the information related to each display controlling apparatus includes a respective processing time of each display controlling apparatus. 
     
     
       6. The image processing apparatus according to  claim 1 , further comprising a display unit, wherein the capturing unit captures image data being displayed on the display unit. 
     
     
       7. The image processing apparatus according to  claim 6 , further comprising a specifying unit configured to specify a region where there has been a change by comparing newly captured image data with previously captured image data,
 wherein the sending unit is configured to send image data in the changed region specified by the specifying unit. 
 
     
     
       8. The image processing apparatus according to  claim 7 , wherein the sending unit is further configured to send pointer information apart from the image data. 
     
     
       9. The image processing apparatus according to  claim 1 , further comprising a video memory configured to store image data to be displayed on a display unit. 
     
     
       10. The image processing apparatus according to  claim 1 , further comprising a specifying unit configured to specify a region where there has been a change by comparing newly captured image data with previously captured image data. 
     
     
       11. The image processing apparatus according to  claim 1 , wherein the display controlling apparatus includes a projection unit. 
     
     
       12. The image processing apparatus according to  claim 1 , wherein the sending unit sends the image data captured by the capturing unit to the display controlling apparatus via a network. 
     
     
       13. The image processing apparatus according to  claim 12 , wherein the network includes a local area network (LAN). 
     
     
       14. The image processing apparatus according to  claim 1 , wherein the sending unit sends pointer information apart from the image data. 
     
     
       15. The image processing apparatus according to  claim 1 , further comprising:
 a second receiving unit, different from the receiving unit, configured to receive user input by way of a remote controller. 
 
     
     
       16. A method for controlling an image processing apparatus that is capable of communicating with a plurality of display controlling apparatuses, the method comprising:
 receiving information related to each display controlling apparatus; 
 determining a representative apparatus among the plurality of display controlling apparatuses based on the received information related to each display controlling apparatus; 
 capturing image data; and 
 sending the captured image data to the display controlling apparatus determined as the representative apparatus. 
 
     
     
       17. A non-transitory computer-readable storage medium which stores a program for causing a computer to execute method, the method comprising:
 receiving information related to each display controlling apparatus of a plurality of display controlling apparatuses; 
 determining a representative apparatus among the plurality of display controlling apparatuses based on the received information related to each display controlling apparatus; 
 capturing image data; and 
 sending the captured image data to the display controlling apparatus determined as the representative apparatus. 
 
     
     
       18. A non-transitory computer-readable storage medium according to  claim 17 , wherein the information related to each display controlling apparatus is received from each display controlling apparatus, respectively. 
     
     
       19. A non-transitory computer-readable storage medium according to  claim 18 , the method further comprising:
